Effect of Pseudomonas aeruginosa on the production of lignocellulase from Phanerochaete chrysosporium
铜绿假单胞菌对白腐菌产木质纤维素降解酶的影响

The effects of Pseudomonas aeruginosa on the production of lignin peroxidase, manganese peroxidase and CMCase from Phanerochaete chrysosporium in a solid substrate fermentation process were studied. Effects of different concentrations of Ps. aeruginosa on other parameters, such as pH, surface tension of crude enzyme liquid, volatile organic matter concentration were also evaluated. The results showed that Ps.aeruginosa AB93066 at 5.72% increased the production of LiP, MnP and CMCase by 67.8%, 57.9% and 17.8%, respectively while strain Ps. aeruginosa ATCC9027 at 2.86% increased the production of LiP, MnP and CMCase by 86.3%, 49.3% and 43.7%, respectively. The surface tension of crude enzyme liquid from P. aeruginosa ATCC9027 was lower than that from Ps. aeruginosa AB93066. The addition of Ps. aeruginosa had no significant influence on the pH value. The volatile organic matter concentration was positively correlated with the enzymatic activity.
